The geospatial backbone of the Diversion-Runoff Calculator (DRC) is the Utah Water Right Distribution Network. The Water Right Network (WRN) is provided by the Utah Division of Water Rights (DWRi), an agency within the Department of Natural Resources. DWRi actively maintains the WRN to reflect the configuration of the physical infrastructure and administrative procedures in accord with the legal framework for water allocation based on the Doctrine of Prior Appropriation.
The WRN consists of the following four geospatial layers and three sets of tables.
NetNodes
Point Layer
Measurement Stations
Point Layer
Net Flowlines
Line Layer
NetFields
Polygon Layer
Data attributes for each these components are described here. The data is viewable online, however, the DRC requires an augmented local version of the data in order to run.
The WRN is subject to change, thus the geospatial inputs to the DRC must be updated periodically in order to reflect these changes, particularly with ongoing development of the WRN.
ERSI's ArcGIS Pro is the prefered platform for interfacing with the DRC. Begin by opening the WRN in ArcGIS Pro.
Go to https://utahdnr.maps.arcgis.com/home/item.html?id=78d2e8a8e0134a4097e3bcb2da6a7ec9#overview and click on "Open in ArcGIS Pro."
This initiates a the download of a .pitemx file (Portal Item File), a small JSON file used in ArcGIS Pro to open items directly from ArcGIS Online or ArcGIS Enterprise. It acts as a shortcut, launching a new instance of ArcGIS Pro and loading the specified content.
Go to your downloads and click on the Utah_Water_Right_Distribution_Network.pitemx file. This opens ArcGIS Pro and loads the WRN layers.
The map layers may not be visible at the initial zoom level. However, the layers should be shown in the Contents pane as shown in the figure below.
Export each of the feature layers (i.e. NetNodes, Measurement Stations, Net Flowlines, and NetFields).
Do this by typing "export feature" in the Geoprocessing pane search bar and selecting the Export Features tool as shown below.
Specify the Input Features as one of the WRN layers.
Specify the Output Feature Class file location in the 'UCRAF_ControlTool' repo under UCRAF_Data → GIS → DWRi Distribution Network → YYYYMMDD :
E.g., C:\...\UCRAF_ControlTool\UCRAF_Data\GIS\DWRi Distribution Network\20250515
Click OK and hit Run.
Similarly, export each of the tables (i.e. NetPaths Table, PathPoints Table, and NetPathlines Table).
Do this by typing "table to excel" in the Geoprocessing pane search bar and selecting the Table To Excel tool as shown below.
Specify the Input Table as each of the WRN tables.
Specify the Output Excel File location in the same 'UCRAF_ControlTool' repo under UCRAF_Data → GIS → DWRi Distribution Network → YYYYMMDD :
E.g., C:\...\UCRAF_ControlTool\UCRAF_Data\GIS\DWRi Distribution Network\20250515
Click OK and hit Run.
Do this for each table individually.
